Ask the Expert: Melanoma Prevention, Causes & Risks, and Treatment

According to the American Cancer Society, the rates of melanoma are rising and about 96,480 new melanoma cases will be diagnosed in 2019. Melanoma accounts for only about 1 percent of all skin cancers, but causes a large majority of skin cancer deaths. John Vander Zee, MD, a physician with the Nassif Community Cancer Center Melanoma and Advanced Skin Cancer Clinic shares more about melanoma prevention, risk factors and treatment.

Prevention:

What sun protection factor (SPF) do you recommend? SPF 15 or higher. My advice is simple: Live your life to the fullest but take precautions. Get the umbrella out when you’re at the beach or the pool and don’t overdo it. Finally, get out of the tanning bed!

What can a patient expect from a full body scan? Peace of mind. A good dermatologist can identify areas of concern as early as possible or anything that you need to keep a close eye on.

What other screening methods are available? I encourage two other methods. First, use a digital camera and snap photos of your body annually. Store the memory card somewhere safe. This way, if a questionable lesion appears, you and your dermatologist can reference the photos. Second, remember the ABCDE rule:

  • A is for asymmetry (one half of the mole does not match the other half)
  • B is for border irregularity (the edges are ragged, notched or blurred)
  • C is for color (the pigmentation is not the same)
  • D is for diameter greater than six millimeters (about the size of a pencil eraser)
  • E is for evolution, meaning a change in the mole’s appearance over time

Causes & Risk Factors

What are moles? Are there different types? Moles are growths on the skin that are usually brown or black. They are formed by clusters of melanocytes, the pigmented cells responsible for your skin color. There are times when moles are not brown/black, sometimes they’re red or pink, and sometimes they’re not pigmented at all. For this reason it is important to have regular visits with a dermatologist.

Does a family history of skin cancer increase someone’s odds of developing melanoma? Any family history increases the odds for developing melanoma.

What are some of the trends you see in melanoma patients? Skin cancer is the fifth most common diagnosed cancer in the area. I also see it in younger populations, as young as 14 years old. 90 percent of cases are due to sun damage and the remaining 10 percent are from moles.

Treatment

What happens once a patient is diagnosed with melanoma? Patients should seek treatment as it is a very specialized cancer. Treatment is changing rapidly so it’s important to visit a doctor who stays abreast of changes. Surgery is most common for both localized and metastasized stages. With all the changes and improvements in surgery, it is oftentimes less needed. For example, immunotherapy has prolonged patients’ lives, with long-term cures in 10-20 percent of patients.
